Valoración agronómica y sanitaria de tres variedades de cebada maltera (Hordeum vulgare L.), con la aplicación de fungicidas, en la localidad de San Simón, provincia de Bolívar

Barley currently occupies the fifth position among the most cultivated cereals worldwide. In the Ecuadorian inter-Andean region, farmers in this area and in marginal production areas, located at more than 3,300 meters of altitude, are dedicated to growing barley. This study was developed for the agronomic and health assessment of three varieties of malting barley with the application of fungicides. It was carried out in the agroecological zone of San Simón, in which six treatments were evaluated with two factors: phytosanitary management and three varieties of malting barley. The objectives set in this research were: i) Characterize the agronomic components of three varieties of malting barley. ii) Evaluate the phytosanitary behavior of the malting barley crop. iii) Select the variety with the best productive and health response for the San Simón area. A randomized complete block experimental design (DBCA) was applied, with three repetitions. Analysis of variance plus the Tukey mean comparison test at 5% was performed. In the variable hectoliter weight (PH), a higher percentage was determined in T1: Phytosanitary management with fungicide + Voyaber with 65.90 kg/hL-1, followed by T2: Phytosanitary management with fungicide + Iniap Alfa with 65.78 kg/hL-1. In relation to yield, an increase is observed when including the use of fungicide, with average yields greater than 4652.2 kg/ha-1. In addition, it was found that morphological variables, such as plant vigor, growth habit and type of straw, influenced the adaptation of the varieties to the environment. In addition, it was found that the morphological variables, such as plant vigor, growth habit and type of straw, are observed according to those established in the technical sheets of the use of fungicide significantly improved the crop yield, which can be a valuable consideration for farmers and variety selectors in the region. The results also highlight the importance of considering morphological factors in the production of malting barley, since they can affect the adaptation of the varieties to the local conditions of San Simón, which contributes to improving the productivity and quality of malting barley crops in This region.
